| Summary: | CaAl4Fe8O19 is solid solution from two compound, CaAl12O19 and CaFe12O19 with ratio 1:2.Calcium element is known used in bioceramic, but in this research,it will use in magnetic materials applications . Yhis compund prepared by Co-Precipitation methode, with the molar ratio of CaO, Al2O3 and Fe2O3 is 1: 2: 4 then the mixed powder calcined. Variable in the experiment is temperature which is calcined at 750oC, 850oC,and 950oC. Calcinations process are in vacuum condition. The powder is characterized using XRD, SEM, and magnetization test using Vibrating Sample Magnetometer. In general, it was found to have hexagonal magnetoplumbite . Magnetic properties resembles Superparamagnetic at room temperature |
